Package Drawing:

NCP1421 is a monolithic micropower high-frequency step-up switching converter IC specially designed for battery- operated hand-held electronic products up to 600 mA loading. It integrates Sync-Rect to improve efficiency and to eliminate the external Schottky Diode. High switching frequency (up to 1.2 MHz) allows for a low profile, small sized inductor and output capacitor to be used. When the device is disabled, the internal conduction path from LX or BAT to OUT is fully blocked and the OUT pin is isolated from the battery. This True-Cutoff function reduces the shutdown current to typically only 50nA. Ring-Killer is also integrated to eliminate the high-frequency ringing in discontinuous conduction mode. In addition to above, Low-Battery Detector, Logic-Controlled Shutdown, Cycle-by Cycle Current Limit and Thermal Shutdown provide value-added features for various battery operated applications. With all these functions ON, the quiescent supply current is typically only 8.5 μA. This device is available in the compact and low Micro8 package.
